Definitions

  • This invention relates to a panel incorporating a plurality of light emitting diodes (LEDs).
  • the present invention provides a panel as defined in Claim 1.
  • the panel may be a glazing panel and/or a lighting panel.
  • the invention is particularly applicable for use with LEDs having a plurality of light emitting dies contained within the same packaging, particularly RGB LEDs which have individual red, green and blue emitting dies adapted to be controlled individually provided within the same packing.
  • a relatively thin or narrow connection portion of the electrical pathway may facilitate connection with connection points of the LED packaging for the individual dies contained within.
  • the spacing between connection points on the LED packaging may be of the order of 1 to 2 mm.
  • a narrow connection portion may particularly facilitate connection between the electrical conduction coating and the interior or central connection points of a multi-die LED.
  • a relatively wide transfer portion of the electrical pathway may help to minimise electrical losses in the electrical pathways.
  • the electrically conducting pathways may be provided by an electrically conducting coating layer provided directly on one of the surfaces of the glass substrate.
  • This may be a sputtered coating stack which may have a physical thickness in the range of 5 nm to 300 nm, for example a coating stack comprising ITO or silver.
  • it may be a pyrolytic coating, particularly one deposited by chemical vapour deposition, which may have a thickness in the range of 100 nm to 5000 nm, for example a coating comprising tin oxide doped with fluorine or antimony.
  • the sheet resistance of the conducting coating layer may be within the range of 1 to 6 ohms/square or within the range of 2 to 20 ohms/square.
  • Interruptions are provided in the conductive coating layer so as to define one or more electrical pathways; such interruptions may be provided by masking during deposition of the coating layer or by ablation, for example laser ablation, chemical etching, abrasion or cutting. Provision of the electrically conducting pathways directly on one of the surfaces of one of the glass substrate, particularly in the form of a coating layer, may facilitate cutting to size and/or handling and/or assembly.
  • the electrically conductive pathways may be provided by an electrically conductive coating layer provided on a substrate, for example a PET film, associated with the glass substrate, for example, laminated or adhered to the glass substrate.
  • the coating layer may be a sputtered coating layer as referred to above.
  • the electrically conducting coating is preferably present over substantially the entire surface area of the substrate, for example over at least 90 % or 95 % of the surface area of the substrate. This may provide a substantially constant or homogeneous visual appearance over the panel.
  • the invention may facilitate a comprise or optimisation between one or more of the following factors:
  • the substrate(s) may be a glass sheet; a flat soda lime glass, noteably float glass, may be used for one and preferably both of the glass sheets.
  • One or both of the glass sheets may be clear glass, extra clear glass or body tinted glass.
  • the glazing panel may be substantially transparent.
  • it may have a light transmission (CIE Illuminant C) of greater than or equal to 40%, 50%, 60% or 70% and/or a level of haze of less than or equally to 5%, 3% or 2%.
  • the panel may be unnecessary and/or undesired for the panel to be substantially transparent.
  • it may have a light transmission (CIE Illuminant C) of less than or equal to 20%, 10%, or 5% and/or a level of haze of greater than or equally to 30%, 40% or 50%.
  • a substantially transparent electrically conductive coating layer may be preferable when some or all of the LEDs are arranged to provide illuminate that will pass through the electrically conducting pathway.
  • the first and second glass sheets may be laminated together to form a laminated assembly by a plastics interlayer which comprises one or more sheets of PVB or a resin, for example EVA.
  • the plastics interlayer may be substantially transparent; it may be neutral or clear in colour or it may be body tinted.
  • the majority and more preferably substantially the entire surface area of the panel is provided with LEDs, that is to say that the LEDs form an array of spaced LEDs with the array covering greater than 50%, 60%, 70%, 80% or 90% of the surface area of the panel.
  • the glazing panel may incorporate at least 50, 100 or 200 LEDs.
  • the substrate(s), particularly when in the form of glass sheets preferably have a thickness within the range of 2.5 mm to 10 mm.
  • the glazing panel may have a mechanical resistance as defined in European Standard EN12600 (often referred to as the pendulum test) of 3B3, preferably 2B2 and more preferably 1B1.
  • the panel may be supplied with a relatively high voltage, that is to say a voltage within the range 55 to 400 volts, perhaps 210 to 250 volts or 290 to 300 volts. This may help to reduce electrical power losses in the coating.
  • a glazing panel 10 comprises first 11 and second 12 flat, clear, 3mm thick soda lime float glass sheets laminated together by means of a 0.76 mm thick sheet of PVB 13.
  • the inner surface 14 of the first glass sheet 11 is provided with a substantially colour neutral CVD coating stack 15 comprising an SiOxCy undercoat and an overlying Sn02:F coating.
  • the coating has a resistance of about 15 ohms per square.
  • Interruptions 16 in the coating stack 15 formed by laser ablations about 70 microns wide define electrically conducting pathways between LEDs 17 which are soldered or attached with an electrically conductive adhesive 19 either side of the laser ablations 16.
  • Each LED is in direct contact with the coating 15 of the first glass sheet 11, the spacing shown in FIG 2 being schematic and not representative of the actual positioning.
  • Additional laser ablations 18 divide the array of LEDs 17 in to individual lines of LEDs 101, 102, 103, etc which are connected in series.
  • the lines of LEDs are connected to bus bars (not shown) positioned at opposite edges 121, 122 of the glazing panel.
  • the LEDs are adapted to provide illumination through the second glass sheet 12, i.e. without passage through or hindrance by the conductive pathways provided by the coating layer 15.
  • the LEDs are arranged in a regular grid at 5cm intervals such that the array of diodes covers substantially the entire area of glazing panel.
  • Each LED has a surface area of about 4mm 2 .
  • each LED 17 is a RGB LED having three individual light emitting dies within its packaging.
  • Each die has an associated connection or lead 21,22 23 arranged at the exterior of the packaging which is electrically connected to the its associated electrical pathway 31,32 33.
  • connection portion 35 of electrical pathway 32 has a width of the order of 1 to 2 mm and is in the form of a narrowing of the transfer portion 34 of the electrical pathway.
  • Transfer portion 34 may have a width of the order of 20 to 60 mm.
  • three individual LEDs 41, 42 and 43 are arranged together in a cluster. These may be individual red, green and blue emitting LEDs.
  • the narrowing of the electrical pathway 52 from the transfer portion 54 to form the connection portion 55 is achieved progressively rather than in a step. This may facilitate current flow within the electrical pathway; it may reduce the risk of creating hot spots; it may be more convenient to manufacture.
